Diarrhea can also cause weight loss. Abdominal pain is another symptom of colon cancer that may prevent you from eating normally. If you have lost a significant amount of weight accompanied with these symptoms, you need to talk to your doctor immediately to determine the cause.
Obtain a history of any nonintestinal illnesses that can lead to diarrhea. Vomiting and/or diarrhea may be a manifestation of that illness or a result of its treatment. Obtaining a history of recent surgery or radiation, food or drug allergies, and endocrine or gastrointestinal disorders is extremely important. The patient should always be questioned regarding prior episodes.
